GoldQuest finds crumbs too!

[Anonymous]

Hi,
I was scanning a rock bar the other day and was only finding nails bullets etc., when I realised that if these items were coming to rest at these spots then gold should be also. I went back to my last find and scratched around and sure enough there was a hidden crevice beneath.
The image shows what was in there, admittedly it's only crumbs, but this area is not that rich, so I'm looking forward to trying this technique where the crevices are granite, and have been around for a long time. Slate and schist wear away much faster and don't seem to hold as much of the yellow.
The 5 cent piece (is it a dime?) was found on our local beach, they are now quite common. I suspect that it originated from one of the service personal stationed at the US Air Force base situated in Christchurch. Operation Deep Freeze, which primarily services the American, and allied forces scientific research facilities down on the Antarctic ice shelf.
Look beneath those nails, all the fines add up in time.
Cheers
Kev

Did you find small gold with Goldquest or by pan-ing

Hi Frank,
I used my GoldQuest to find a horseshoe nail which was lodged at the top of a hidden crevice, that held the gold.
The largest grain is 5mm x 2.5mm x 0.5mm at its widest points, and it is detectable at one inch when presented flat side on to my homemade DD set in mono mode. That's effectively an 8.5 inch mono, now that's nearly as good as an old VLF. I don't think it will be very long before Eric's stock prospecting machines will be as good as the latest VLFs at detecting crumbs.
Cheers
Kev.

I am working on a probe for my CS,with a metal base
core.bench test now it will detect a nugget size of
your large one about 1-1/16".a nickel 7".
On a Goldquest I suspect that it will go much
deeper.I am still tinker-ing with it.That's all
that I will say about it.Good luck with your nugget
hunting.
Frank.

Hi Frank,
Sounds good, if I'd had your probe it may have indicated that the larger grain was in the crevice since it wasn't that deep and the crevice was on a sloping angle.
Interestingly when I look at the larger grain under a microscope, I can see blebs and crystalline structures that indicate it was likely a number of smaller grains at one time that have been fused together. The blebs are usually indicative of microbial addition and the crystalline structures are usually indicative of authigenic precipitation.
What this all means is that this grain should not be as easy to detect as a grain directly from a reef, or lode. Atomically it is unlikely to be one homogenous whole and may contain interior impurities inside such as clay or rock particles.
I'm not saying this is invisible gold, but to be able to detect it at all at 1 inch, I find impressive.
I might build myself a probe for crevicing too. Good idea Frank.
Cheers
Kev.
